Application filed October 8l. 1907. Serial No. 400x013.

Be it known that l, Aoonr Beren, e citizen of the United States, residing et Pitts burg, in the county' of Allegheny and State. of Pennsylvanie, have invented e neuv end useful.Pressuredtegulator, of which the iollowing is s specification.

This invention reletes to pressure regulatend hss for its principal object to provide e mechanism of'novel construction `'or controlling the llow of ges, steam or cold writer or other; fluids through s heating" system, or the supply of liquid or gaseous fuel to other device, or any other piece where it is advisable to employ the pres sure of liquid, vapor or gaseous lluids to control their own ilow or the ilow of any lluid suoli es liquid, ges, steam, nir, or vapor.

The principal object oi the invention is to provide e pressure regulator of ver)r simple construction, and oi extreme sensitiveness,

and which, while of compact structure, will permit of considerable rsnge of movementior the purpose ol' opening or closing e velve or similar controlling device.

A further object of the invention is to provide e pressure regulator in which c serios of expansible chambers nre so connected together that the sum of the expansions in ell oi the chambers will `be transmitted to the member to be controlled.

With these and other objects in vieiv, es will more fully hereineiter e peer, the inven tion consists in certain nove features of construction and arrangement of ports, hereinafter fully described, illustrated in the eccompanying drawings, und perticu'lerly pointed out in the appended claims, it being understood that various changes in tliei'orm pro` portions, size and minor details oithe structure niaybe inode Without departing from the spirit or sacrificing any of the advantages of the invention.

n the accom anying drawings-Figure l is e sectional e ovation of e pressure regulator constructed in accordance with the 1nvention. Fig. 2 is e similar view of the seine in expended condition. Fig. 3 is s section on line 3 3, Fig. l. "ig. 4 is e Viewpertly in'section and pcrtly in elevation ci e modi.- ed orrnof pressure regulator.

beineouch i'ormcd of n ,members ll und the llungo of one littingI within the other, end the linnges being brnzcd, soldered or otherwise rigidly secured together, to lorm closed charnbers. A bund l2il preferably surrounds the llengcd portions of the members ll end l2 und is brained or otherwise secured in place, the same tendiney lo reinforce the peripheral portions ol seid members et their points of sttavlmieut. Each of the members li end l2 constitutes n diaphragm, und to the centrsl portion oi euch diaphragm firmly secured o hub or cent-rol coller l5 ell of seid hubs or rollers beine7 iuternellj.r threaded, sind those belonging to the adjacent diephragm of superposcd chambers being connected bv smnll threeded sections lo, while the hubs or collars oi' the dicphregms bepnir of interlitting longing' to' euch chamber are meint-ninedin vto connect to the pipe, reservoir,cr other container for the lluid to be used in operetingbr the device. Sit the opposite end of the regulntor the cud hub or coller 15 is iinperforetc, and is arranged to engage against or to transmit motion to the device to be controlled, this in the present instance being iilustrzited `in the stem 19.

When the lluid under pressure is admitted through the nipple L5 it passes into ell of the chambers l1 und the two diephregms ll und l2 ol euch chamber will be forced outward. inasmuch ns the nipple l5 end the end hub member l5 are held rigid, the expansion of the iirst chamber will transmit movement to the second hub, and from thence vto the entire'series of chambers, end this movement 'will be augmented by expansion of the second chamber, end further augmented by the expension of the third chamber, end so on, untilthe end member-i5 is moved egsinst thevelve stein or other device to be oontroed, the extent of movement transmitted 'to the letter. being inl proportion to operating flui ih'e construction liereinbefcre set forth perticnlerlif vdesigned for closing s valve so to ctjfoii the iov of e luid other then form ot zr valvel 12 having?r peripheral ilsnges, i

sion of the regulator Will result in ycutting off the flow of the fluid operating the regulator.

This construction has been shown in Fig. 4 a 1d is particularly designed for use in-connection with steam. By referring to Fig. 4 it will be noted that the valve casing 20 has av tubular extension 21 thereon to which a erforated end collar 22 is secured, said colar being employed in lieu of the collar 15 heretofore referred to. A series of closed chambers 23 connected in the manner hereinbefore describedv is mounted above the collar 22, the upper chamber being provided with an imperforate collar 24 to which a valve stem 2.5 is secured. This stem extends downward through the threaded pipe sec.v tions 26 which connect the chambers 23' and a valve 27 is connected to the lower portion of the stem and normally bears against a spring 28. When the walls of the chambers 23 are in their normal positions the valve 27 is open. Steam or other fluid is thereforey free to pass under ordinary pressure and upward into the chambers 23. When, however, the pressurepasses a predetermined degree the chambers 23 will be expanded and valve 27 shifted toward its seat so as to partly or entirely cut off the How of fluid through the easing 20.

The several diaphragms of which the chambers are formed have an inherent tendency to resume positions parallel with each other, so that When the pressure is reduced, the regu1ator-will contract, and Awhen the pressure is increased, the regulator will expand, the degree of expansion being directly proportioned to the degree of pressure of the adjustable pipe connections between the hubs and extending in to the bore thereof, said connections being disposed in alinement, a supply pipe adjustably connected to and opening through the diaphragm at one end of the series, and a valve fixedly ,connected to the diaphragm at .the outer end of the series.

In testimony that I claim the foregoing asv my ownfl have hereto affixed my signature in the presence of two witnesses.
